Question

How do we taste acidic nature of acetic acid $\left(C{H}_{3}COOH\right)$?

• A. Reaction with sodium hydroxide (NaOH)
• B. Litmus paper test
• C. Reaction with alcohol
• D. Reaction with sodium

Answer 1

Answer: (A), (B)

The correct options are
A

Reaction with sodium hydroxide (NaOH)

B

Litmus paper test

When we put litmus paper in aqueous solution of acetic acid, it shows change in color from blue to red.

When acetic acid reacts with sodium hydroxide which is a base, salt and water is formed. This is an example of neutralization reaction

$\underset{\text{(acetic acid)}}{C{H}_3-\stackrel{\stackrel{O}{||}}{C}-OH}+\underset{\text{Sodium Hydroxide}}{NaOH}⟶\underset{\text{Sodium Acetate}}{C{H}_{3}COONa}+\underset{\text{Water}}{H_{2}O}$
